“…Due to the complex work of the monosymmetric beam (beam subjected to bending and torsion) and thus the possibility of measurement errors, it was decided to conduct another series of tests on bent beams with a thin-walled rectangular cross-section and develop an advanced numerical model in the Abaqus program in order to formulate conclusions regarding the selection of the right anchoring length of composite tapes which are used to reinforce steel thin-walled elements. The subject of testing on engineering structures with hollow sections in terms of reinforcing them with composite materials is the subject of testing and analyses by many researchers [ 17 , 18 ].…”

In order to design an optimal reinforcement of steel thin-walled beams with composite materials, it is worth analyzing two important, although often overlooked issues, which are the selection of the appropriate thickness of the adhesive layer and the effective anchoring length of the composite tape. This paper, which is part of a wider laboratory study devoted to the strengthening of thin-walled steel profiles, focuses on the second issue. The paper involves a description of laboratory four-point bending tests during which ten thin-walled steel beams made of a rectangular section with dimensions of 120 × 60 × 3 and a length of 3 m were tested. Two beams were taken as reference beams, and the other eight were reinforced using Sika CarboDur S512 carbon fiber composite tape, assuming four different effective anchorage lengths. The impact of the length of the anchoring of the composite tape on the value of the displacements and strains of the tested beams and on the value of the destructive load that caused tape detachment was analyzed. The following phase was numerical analyses carried out in the Abaqus program, which showed high consistency with the results of laboratory tests. In reference to the conducted tests, it was observed that the increase in the anchoring length of the composite tape has a slight impact on the change in the value of strains and displacements in the tested beams. Nevertheless, the increase in the effective anchorage length has a significant impact on the load value at which the composite tapes are detached from the surface of the steel thin-walled beam.

“…Based on the mechanical behaviour of marine hoses, Gao et al [76] investigated the structural behaviour of ring-stiffened composite marine rubberised hose under internal pressure and validated the model. Nassiraei and Rezadoost [77,78] numerically investigated the effect of the composite material in marine structures using ANSYS, by considering the static capacity and local joint flexibility (LJF) of tubular joints having fibre-reinforced polymer (FRP) reinforcements under different loads. Gonzalez et al [79] investigated the axial characteristics of flexible bonded marine hoses and presented some hose bending profiles.…”

Currently, the properties of composites have been harnessed on pipelines in the marine offshore industry. In this study, marine bonded composite hose (MBCH) is presented. It is aimed at understanding the stress/strain distribution on marine bonded hoses using local design pressure under burst and collapse cases. This study also investigates composite material modelling, hose modelling, liner wrinkling, helical spring deformation, and two MBCH models—with and without ovalisation. The ovalized model is considered the simplified model in this research. A mesh study was carried out on meshing the hose layers. In this study, local design pressure was considered and not operational pressure. This finite element model was adopted to predict the deformation and mechanical response behaviour of MBCH. From this study, composites could be considered to improve conventional marine hoses. The study findings include identification of buckled sections on the hose and stressed zones on the helix reinforcement. Highly reinforced hose ends are recommended in ends of the MBCH as they had maximum stress and strain values.

“…Lightweight materials are the eternal goal of the aerospace field, where even the reduction of each gram is rigorously considered [ 1 , 2 , 3 , 4 , 5 ]. As the applications of resin matrix composites, mainly carbon or glass fiber-reinforced polymers (CFRP or GFRP), have increased in aerospace component manufacturing, the preparation of high-strength heterojunctions between metals and thermoplastics has become a major concern [ 6 , 7 , 8 ].…”

The generation of high-performance heterojunctions between high-strength resin matrix composites and metals is of great significance for lightweight applications in fields such as aerospace and automobile engineering. Herein, we explored the feasibility of employing a laser joining process to achieve high-strength heterojunctions between continuous carbon fiber-reinforced PEEK (CCF30/PEEK) composites and titanium alloy (Ti6Al4V). A joint strength of over 50 MPa was achieved through constructing mechanical interlocking structures between CCF30/PEEK and Ti6Al4V. Tensile tests revealed that the fracture of joints was mainly ascribed to the detachment of carbon fibers from the resin matrix and the breakage of carbon fibers. The structures with different orientations and dimensions were confirmed to significantly influence the formation of interlocking structures near the joining interface and the resultant fracture strength of joints. It is believed that the results presented in this study provide a strong foundation for the production of high-performance heterojunctions.
